Soy milk works great in pancakes. My basic recipe for pancakes is about a cup of flour, about a cup of soy milk, a tablespoon or two of sugar and veg oil, and a few teaspoons of baking powder. Works great, makes nice, fluffy pancakes. (I know, not a "recipe" so much as list of ingredients with approximate proportions, but that's how I tend to cook, experimenting and learning from experience as I go...)

Edit: I don't know about scotch pancakes; I've never made them, but upon looking up a couple recipes, I don't see why it wouldn't... Soy milk behaves much like milk in these kinds of recipes, the only difference being that soya adds a bit of binding that dairy milk doesn't (and perhaps a smidge of a taste difference?)
