In a large bowl, combine the yogurt, ginger paste, garlic paste, lemon juice, red chili powder, coriander powder, cumin powder, garam masala, turmeric, and salt. Mix well.
Add the chicken pieces to the bowl, and use your hands to massage the marinade into the chicken. Cover the bowl with plastic wrap and refrigerate for at least 2 hours, or overnight.
Preheat the oven to 400°F (200°C). Line a baking sheet with foil and brush with oil.
Arrange the chicken pieces on the baking sheet, and brush them with a little more oil.
Bake for 30-35 minutes, or until the chicken is cooked through and slightly charred around the edges.
Serve hot with mint chutney and onion rings.
