It's great that you're incorporating more vegetarian and vegan foods into your diet! I've been vegan for 8 years and was vegetarian for 8 years before that, and the biggest benefit I've gotten from veganism is that it's really expanded my cooking (and eating) repertoire. Once you cut meat, dairy, eggs, etc. you need to learn to cook with new ingredients, and while it can seem daunting, it's a great skill to have, even if you never become fully veg.

A typical couple days for me look something like this:
Breakfast: homemade granola with soy or coconut yogurt, fruit.
Snack: apple slices with natural peanut butter.
Lunch: Leftover veg chili with sweet potatoes.
Snack: Luna bar.
Dinner: BBQ broccoli and seitan, brown rice.

Breakfast: WW bagel with hummus and tomato.
Snack: Green smoothie with rice protein powder.
Lunch: cucumber and avocado sushi.
Snack: 1 orange, tamari almonds.
Dinner: Tempeh buffalo "wings," greens, cornbread or roasted potatoes

Breakfast: WW toast with marmite and tomato
Snack: Green smoothie (love them)
Lunch: butternut squash soup with toast or quinoa on the side, spinach salad
Snack: Luna bar.
Dinner: Roasted chickpeas with garlic and broccoli.

I probably actually eat more than that during any given day, but that gives you a rough idea of some meals. If you are looking for recipes, I highly recommend any of the books Isa Chandra Moskowitz has put out. She's a great cook, and her recipes are pretty foolproof. Her book the Veganomicon also has an extensive guide for how to cook different grains, beans, and veggies. You can also check out her blog at www.theppk.com, where she's posted a number of recipes.
