www.buckwheatpete.com has good recipes (there's a small fee, but worth it in my opinion). I use his pita recipe for our pizza crust and it's delicious. We're dairy free, soy free, gluten free, corn free. My DS can't have rice either, so I don't use a lot of rice flour. And he can't have potato, so we can't do most gluten-free mixes.
You usually need a couple of flours mixed together. And you need a binder to replace the "glue" of gluten (in most mixes, that's xanthan gum, which we can't have because it's corn, so I use Wilton's Gum-Tex which is made of karaya gum).
I've been making popovers most mornings that are delicious - with sorghum flour and tapioca starch. The eggs bind it. We've been making tortillas out of sorghum flour, tapioca flour, sweet potato starch, and karaya gum. Again, delicious. We make gluten-free chocolate chip cookies. Buckwheat waffles/pancakes (they freeze well too, to pop in the toaster). We make chickpea fritters out of chickpea flour (besan and gram are other names for it) and zucchinis, that are a good side dish (DS likes to dip them in spaghetti sauce).
The texture is not quite the same in a lot of recipes, so you may have to adjust your palate a little. For gravy, I've found that a mixture of sorghum flour and sweet potato starch works the best.
My blog

We purchase rice crackers for DD2. She likes to dip them in hummus.
www.allergygrocer.com also has some good mixes by Miss Robens. I bought a soft pretzel mix but haven't tried it yet. They also have ingredients.
And
