The Deepak book is a wonderful intro to the lifestyle, but for healing modalities you have to get both of Dr. Vasant Lad's main books, "Ayurvedic Healing" and "Yoga of Herbs." :) Then for cooking wonderful Indian recipes that tell you whether or not they increase Vata etc., get "The Ayurvedic Cookbook" the author escapes me at the moment.
Dr. Andreas Moritz here on CureZone also has a book that is Ayurvedic based, altho it doesn't say so in the title. "Key to Rejuvenation" is one I plan on getting soon. :)
