Hi RiaLynn!

I haven't personally tested these recipes but it looks like there are some good ideas in here:

You can omit or swap some of the items to lower the carbs.

These recipes are specifically low carb:

My toddlers love it when I marinade our tofu in? cup of coconut aminos and 1 tbsp of honey. You can throw it in the skillet or the oven. It goes great with egg roll in a bowl. Nutritional yeast can be used to make it more crispy. Cornstarch can make it more crispy. Tossing it in bullion before cooking can make it more like chicken nuggets, or you can soak in a little broth before cooking. You can use pretty much any marinade you would use for meat. Just don't use a ton because it will take on the flavor very quickly.
