For the compote: Bring the cranberries, orange juice, sugar and orange zest to a low boil in a medium saucepot over medium-high heat. Reduce the heat to medium-low and cook until the berries split open and thicken to a compote consistency, 7 to 10 minutes.
For the pancakes: Combine the flour, sugar, cornstarch, pumpkin spice, baking powder, ginger and salt in a medium bowl. Make the egg replacer and combine it with the almond milk, pumpkin puree and vanilla in a small bowl. Using a whisk, combine the wet and dry ingredients and mix gently until combined. You want some lumps. Gently fold in the melted butter. Make sure the batter is still lumpy and thick.
Heat a griddle or skillet over medium-high heat and coat lightly with cooking spray. Use a dry measuring cup to pour 1/4 cup of the batter in a circle. Cook until the surface of the pancake has small bubbles all around, 3 to 5 minutes. Sprinkle with a few pepitas, then flip. Ideally, you should only have to flip once.
On your serving plate, stack the pancakes high to seem impressive, or as Darth Vader would say, ¿most impressive.¿ Top with butter, more pepitas and compote.
