Salads with some vegetarian proteins like beans and nuts (if the fats in nuts are ok) could work - you can vary them quite a bit with different vegetables. Maybe some corn, black beans, fresh green and red peppers with cilantro and lettuce one night. Another night tomato, carrot, cucumber, arugula. If you mix it up you can get a lot of different flavors so it's not repetitive.
Rice will probably helpful for making a meal more filling, plus without meat or other grains, rice can provide the type of protein that most vegetarian sources can't.
GMO might make buying packaged products difficult, it's hard to know the source of all the ingredients, but there might be some gluten-free products that are labeled as gmo-free also. With that and the sugar, msg, aspartame, there will be a lot of label reading. Maybe you could find one or two reliable items, but otherwise stick with the basics, like fresh vegetables, rice, beans. If the sugars naturally in fruit are okay, fruit makes a great snack. Could also be added to salads for variety.
Things like baked tofu or tempeh are good too. I'm not sure what marinades you might use - I like to make my own honey-mustard dressing, but the honey probably has too much sugar. If you're not using a sauce, tempeh is better than tofu, it has a nice kind of nutty flavor. Tofu's rather flavorless by itself. You could serve this with some rice dish, like rice with peas or with tomatoes, onions and peppers, maybe some greens on the side.
