Have a fly tying bench set-up at home, plus carry a "tackle box" along on my camp outings that contain some basic materials and tools. In my travels had the pleasure of listening too, and then later meeting John van Vliet on the subject. He also published a book called "Fly-Tying Techniques & Patterns" that I think is outstanding, so much so I have two copies ... one for the tying bench at home and the other goes with me on most of my trips where I tote the tying tackle box along. Great book for the basics.
