In a medium bowl, mash half of the banana until smooth, then whisk in the egg whites, Greek yogurt, and vanilla extract until well combined.
Stir in the oat flour, baking powder, cinnamon, and sea salt until a thick, uniform batter forms.
Heat a large non-stick skillet over medium heat and lightly coat with a small portion of the ghee.
Pour the batter to form three or four pancakes, cooking for 3-4 minutes per side until small bubbles form and the edges are set.
While the pancakes cook, slice the remaining half of the banana into rounds.
Remove the pancakes from the pan, add the remaining ghee, and sear the banana slices for 1 minute per side until they become deeply golden and caramelized.
Plate the pancakes, top with the caramelized bananas, and sprinkle with hemp seeds for added texture and protein.
