Preheat your air fryer to 400°F.
Slice the chicken breast into even strips and place them in a medium mixing bowl.
Add 2 tablespoons of the Greek yogurt, smoked paprika, garlic powder, sea salt, and black pepper to the chicken, tossing until every piece is well coated.
In a shallow dish, whisk together the almond flour and arrowroot starch, then dredge each chicken strip in the mixture until fully covered.
In a separate small bowl, stir together the oat flour, the remaining 2 tablespoons of Greek yogurt, and the baking powder until a thick dough forms.
Lightly spray the air fryer basket with avocado oil and place the chicken strips and the shaped biscuit dough inside, ensuring they do not touch.
Mist the tops with avocado oil spray and air fry for 12-15 minutes, flipping the chicken halfway through, until the coating is golden and the biscuit is firm.
