"Buddha's Table" by Chat Mingkwan is an excellent introduction to Thai vegetarian cooking - because dairy is not typical in the Thai diet I believe every recipe in the book is vegan. I have tried a few and they have all turned out great. My favorite part of the book is the Curry Pastes section where it tells you how to make all of your favorite curry pastes from scratch - like m Green, Red, Massamun, Panaeng...

If you love thai food I recommend buying this book. Its cheap - I picked up a copy at amazon for $10.
