I think the key must be including ingredients that fill you up more, or other things with breakfast. Pancakes do take a while here, but but my kids and I each have 2 medium sized ones each, but we top with things like nut butter, or sliced almonds with bananas (softened in the skillet), or have them with a glass of soy milk or a little bit of green smoothie. We use ground whole grains, usually oatmeal, and usually no eggs.
We have tried versions of this:

Which are VERY filling. Some grain combinations were not too tasty; you'd want to experiment a little bit.
I'm definitely trying Abbiroads' waffle recipe.
