Preheat grill pan or indoor electric grill to high. Combine yogurt, curry paste, lemon juice, and cilantro in a shallow dish. Add chunks of chicken and coat evenly in yogurt sauce. Lace meat onto metal skewers. When you are about 10 minutes away from eating, place chicken on hot grill and cook 5 or 6 minutes on each side, until charred at edges and chicken meat is firm.
