Cooked grains are always good. I think I read a recipe that baked oatmeal with apricot or peach nectar. You can stir in walnuts, or sunflower seeds, or even shredded coconut.
(I might have seen this in the Mothering recipes!)
OTOH, there's no reason you can't do muffins. There are plenty of non-soy spreads that are very good. I buy Earth Balance, and I'm not sure about the soy content in that, but my in-laws buy Canola harvest. It's a canola oil emulsion. It's whipped, but it has no trans-fats.
