I have primarily tied dries and wooly buggers. Never tied a nymph. What is the easiest one to start with, fewest materials and lowest skill level. I admit it I have to build confidence. It would be a bonus if it worked in western waters. Thanks guys!
A caddis larva, otherwise known as a green rockworm, is real easy to tie and productive out here in the Sierra. Green dubbed body,short darker thorax, and a black collar with guard hairs picked out for legs. A black bead head is good to get it down.

Pheasant tail nymphs
Green or Brown hares ear
Prince nymphs are all good starters that do not take a lot of materials
Partridge and Peacock or any soft hackle while not common and maybe to some a little out of style are real easy ties that still work quite well today as they always have.

midstream,
You might want to try [url=http://www.flyanglersonline.com/flytying/beginners/:c6d17]this[/url:c6d17] before you go any farther. When you get to lesson 7 you will see the easiest possible nymph. When you get to lesson 20, you will not want to stop and you will be on your way to being a competent tyer able to leap medium sized buildings in a single bound. 
Enjoy the journey.

Mcsteff,
Thanks for pointing that out, why didn’t I think of it. Midstream, they will all be easier than dry flies.
You know, one of my most effective nymphs is a small woolly bugger. I think in fact it was originally intended as a hellgramite immitation. But tied in the right colours it could easily be a hexagena, damsel, etc. I’ve got a very small bugger that does a good immitation of an isonychia mayfly nymph.
Note that these nymphs are good swimmers so the flowing marabou tail is the perfect choice.
IMHO…peacock body and soft hackle of your choice.
Pheasant tail and hare’s ear are easy to tie. They also catch fish.
Plain old Gold ribbed hare’s ear.Great fly to learn how to tie nymphs. All the elements are in it…and even if the first few don’t come out quite the way you want they will still work!
Midstream,
I would suggest the gold ribbed hare’s ear which is a great all around fly. Once you have learned to dub the hare’s ear dubbing for this fly, you can use the same method for hundreds of other flies. BTW, most basic nymphs are pretty easy to tie, at least after a little practice 8T 
You had better learn to be a happy camper. You only get one try at this campground and it’s a real short camping season.
Absolutely no skill required. They work in CO, but don’t know if you have midgesin TX.

when I took fly tying classes at a local fly shop, the first nymphs we tied (I forget the exact order) were b/h caddis larva, GRHE, and pheasant tail. All of these patterns are simple to tie and most importantly catch fish. If I had to pick the easiest of the bunch then I would say the caddis larva would be my choice. It can also work as a midge pattern if tied small enough as I frequently do .
Take care everyone and cya around. Mark
midstream, I’ll tell you what; all of the suggested flys are good one. The easiest fly to tye,IMHO,is a stone cased peeking caddis. Use a #16 hook, apply black thread to the shank of the hook and then apply 5 min. epoxy to threaded area. Roll the hook in very small gravel and apply a green head up by the hook eye. Tip: make sure the epoxy is getting stiff before you apply it.
This nymph is gauranteed to sink.
Take a look at this site. Go to “tutorials” and pick out the one you want. Very thourogh, step by step instructions. Good Luck [url=http://www.troutflies.com:930a6]www.troutflies.com[/url:930a6]

Wow! Thanks Guys.
Don’t forget to go to the Fly of the Week (FOTW) archives on this site for excellent choices, photos and tying instructions.
I live right down the road from you in Ft. Worth and have found that the Gold Ribbed Hare’s Ear nymph and Dave Whitlock’s Red Fox Squirrel Hair nymph, both in larger sizes (#8 and #10) are great in the local waters for bream and bass. They are both very easy to tie. If you leave off the wing cases they are even easier and the fish don’t seem to care, at least around here. The Hare’s Ear Flashback is great, too, but I’d practice on the other ones first. Just make them big and buggy and ugly, the uglier the better.

Soft hackles are easiest.
Pheasant tails are only slightly harder.
Hares ears are next.
Once you get the regular hare’s ear down pat, try adding some weight.
Tie them all in different colors and you have a pretty good nymph selection.
Worry about princes and zug bugs next.
The beauty of soft hackles is that you can tie them with different body materials to mimic the nymph patterns you don’t know how to tie yet. They won’t be a perfect substitute, but they’ll be pretty good.
