When your coals are ash covered, but still very hot, pour 1/3 cup of the pancake mix into a container (or a clean hand). Start adding water, one spoonful at a time, and stirring the mix around with a stick or a clean finger, until the mix forms a ball of dough. You're looking for a soft bread dough texture, a little softer than Playdough. If it's too sticky, add more dry mix. You'll know you have the right consistency if you can pat it into a ¼-inch thick pancake. Sprinkle some of the dry mix on your hands before patting the bread flat, to avoid gluing your hands together.
