Slice the chicken breast into thin strips.
Whisk one egg white in a shallow bowl; combine almond flour, paprika, garlic powder, onion powder, salt, and pepper in another.
Dip each chicken strip into the egg white, then dredge in the almond flour mixture until fully coated.
Lightly coat the chicken with avocado oil and air-fry at 400°F for 12 minutes until the exterior is golden and crunchy.
Stir together oat flour, Greek yogurt, the second egg white, baking powder, and lemon juice to create a thick waffle batter.
Pour the batter into a preheated waffle iron and cook until the steam stops and the waffle is firm.
Plate the crispy chicken atop the warm waffle and finish with a drizzle of pure maple syrup.
