Preheat oven to 400°F (200°C) and line a baking sheet.
Blend cottage cheese, eggs, oat flour, garlic powder, baking powder, salt, and olive oil until smooth. Spread into a 1/4-inch thick rectangle and bake for 18–22 minutes. Broil 1–2 minutes for crispiness, then rest.
Pat chicken dry, season with paprika, cumin, chili powder, black pepper, and salt. Cook in a skillet 5–6 minutes per side until cooked through. Rest and slice.
Mix Greek yogurt with lemon juice and a pinch of salt to make the sauce. Slice flatbread, layer with sauce, chicken, lettuce, tomatoes, onion, and herbs. Fold into wraps and sear if desired.
Notes
For extra crispiness, broil the flatbread and sear the wraps in a skillet.
