Stir together lemon juice, paprika, chili powder, garlic, ginger, and salt in a large bowl until well combined. Add chicken; rub until well coated and marinate in the refrigerator for 3 hours.
Preheat a grill for medium heat and lightly oil the grates.
Place chicken onto the preheated grill; discard marinade. Cook, turning occasionally, until skins are slightly charred and the juices run clear, about 30 minutes. An instant-read thermometer inserted into the center of chicken should read at least 165 degrees F (74 degrees C).
