Blend the cottage cheese, eggs, pumpkin puree, milk, maple syrup, and vanilla until smooth.
Whisk the oat flour, protein powder, baking powder, pumpkin pie spice, and salt in a bowl. Stir in the blended mixture until just combined.
Mix the Greek yogurt, maple syrup, pumpkin pie spice, and vanilla in a small bowl until smooth.
Heat a lightly greased skillet over medium-low heat. Cook the pancakes in 1/4-cup portions until the surface bubbles and the edges are firm.
Flip and cook for 1 to 2 minutes more, keeping the heat low enough to prevent the pumpkin from scorching.
Serve with the spiced yogurt topping, pecans, and pumpkin seeds.
