It sounds like you've reduced your meat eating and are almost vegetarian...good for you! As far as what you need calorie wise, it's a pretty individual thing. Fitday and The Daily Plate are good sites to get a general idea of what a person your age, height and activity level may need (hint: choose "sedentary" or the lowest level of activity if you do this formulation unless you are VERY active!).
"I do feel that spiritual progress does demand at some stage that we should cease to kill our fellow creatures for the satisfaction of our bodily wants." -Gandhi
