In a large mixing bowl, combine buttermilk, salt, pepper, paprika, and garlic powder. Add the chicken thighs, ensuring they are fully submerged. Cover and refrigerate for at least 30 minutes.
In another bowl, mix together the flour and cornmeal. Remove the chicken from the marinade, allowing excess to drip off. Dredge each piece in the flour-cornmeal mixture, pressing lightly to adhere.
In a frying pan or deep fryer, heat oil to 350°F (175°C).
Carefully place the chicken in the hot oil, cooking in batches to avoid overcrowding. Fry for about 5-7 minutes on each side, or until golden brown and the internal temperature reaches 165°F (74°C). Remove and place on a baking sheet lined with a cooling rack.
Preheat the waffle iron. In a bowl, whisk together flour, sugar, baking powder, and salt. In another bowl, beat the eggs and add milk and melted butter. Combine the wet and dry ingredients, mixing until just combined.
Pour the batter into the preheated waffle iron, according to the manufacturer's instructions. Cook until golden brown and crisp.
Plate a waffle and top with a piece of fried chicken. Drizzle with maple syrup and add optional butter or whipped cream as desired.
