I am vegetarian and expecting so I have been making a special effort to up my protein. Here is what I am doing:
-Greek yogurt and cottage cheese, which it sounds like you are doing as well
-Nuts for snacking
-High protein dinners that I pack for lunch as leftovers as well. For example, bean pasta bake with tvp crumbles.
-A bean salad that I sometimes make on the weekend and then eat with crackers for lunches or snacks during the week
-These chicken free beyond meat strips are good straight from the package, no cooking/heating required. We keep them on hand for a high-protein snack:

-My husband and i have loved this carob shake we found a recipe for in a vegan pregnancy book. It is simple and quick to make - soy milk, pb, banana, ice and carob powder. It is delicious and a great high protein breakfast
Hope this helps!
