Marinate the chicken in buttermilk for at least 30 minutes.
In a bowl, mix flour, salt, pepper, garlic powder, and paprika.
Remove chicken from buttermilk, letting excess drip off.
Coat each piece of chicken in the flour mixture.
Heat vegetable oil in a large skillet over medium-high heat.
Place coated chicken in the hot oil; fry for about 7-10 minutes on each side.
Check internal temperature (should reach 165°F).
Remove from oil and place on a wire rack to drain excess oil.
Let the chicken rest for a few minutes before serving.
