1) Rub margarine into flour until you have a "sandy" consistency. Mix in salt, sugar and spice. Blend egg replacer with enough soymilk to make 1/2 cup, add and work up to a soft dough. Roll out 1/4 inch thick (1/2 cm) and cut out rounds with a floured glass.
2) Bake cakes on the stovetop using a lightly-oiled griddle or "bakestone", turning once, until brown on both sides and cooked through. You can also bake on a cookie sheet in the oven but the finished product will be dryer in texture.
