Finely chop the shrimp into small, bite-sized pieces and thinly slice the scallions.
In a medium mixing bowl, whisk together the chickpea flour, garlic powder, ground ginger, sea salt, and black pepper.
Add the egg whites and water to the dry mixture, whisking until a smooth batter forms without lumps.
Fold the chopped shrimp and sliced scallions into the batter until they are evenly coated.
In a small bowl, combine the coconut aminos, rice vinegar, and toasted sesame oil to create the dipping sauce.
Heat the avocado oil in a large non-stick skillet over medium heat.
Pour the batter into the skillet, using a spatula to spread it into two even circles.
Cook for 3-4 minutes until the bottom is golden brown and the edges look set.
Carefully flip the pancakes and cook for another 3 minutes until the shrimp is opaque and the pancake is cooked through.
Remove from the heat, slice into triangles, and serve with the dipping sauce.
