Depending where you are in the US you can probably get a seitan product called Veat in your health food store. I swear it tastes just like chicken, even my carnivore father can't tell the difference. They will give your free coupons if you go to:
www.veat.com
Many chinese restaurants use veat in their vegetarian dishes instead of tofu. You can make seitan at home and there is a very good book called Cooking with Seitan by Barabaa Jacobs, but I find I can get good seitan easy enough without the work.
There is a also a company called Yves and another called Liteline that make seitan products, some of the products are better than others so you have to experiment. I get the two companies confused by which ever one does the chicken strips and the canadian bacon (makes a great Rueben sandwich) is the better one.
Also Morningstar Farms has a few faux meat products (not all with wheat gluten), including a good bacon that works on BLT's and in quiches. I like to test non-meat products on kids, if they can't tell it not real meat I know it's good. My niece thinks Boca burgers are just like McDonalds, don't know if that's a good thing or not.
