She doesn't post much anymore, but http://www.manjulaskitchen.com/ is full of vegetarian Indian recipes. She also often includes suggestions if you want to make a recipe low-fat, too. This was my introduction to Indian cooking, and I loved it!

The NYTimes "Recipes for Health" column (http://topics.nytimes.com/top/news/health/series/recipes_for_health/index.html?8qa) is another great resource. Not all of the recipes are vegetarian, but many are.
