Oh, how to start on warm water fish. First of all gills will hit anything that is the right size (think #14 to # and color (almost any color, red, yellow, black, white, green)and moves. Impart some action to make it look like a fleeing insect, bait fish or worm. Finally, make a noise when you present the fly in the water (falling food announces it's arrival)

Bass on the other hand like all the same things gills do but they like it bigger flashier, louder and faster. When you are the top predator you have the chose of food. You can pick and choose what you want for dinner. So for bass you need top water, just below the surface and deep flies.

This is why we have poppers (top water) Streamers (just below the surface) and Clousers (Deep Water).
