In a mini food processor, combine the salt, pepper, paprika, garlic powder, thyme, rosemary, oregano and ginger and pulse until finely ground. Add the olive oil, soy sauce, mustard and lemon juice and process to a smooth paste. Spread the paste all over the lamb and let stand at room temperature for 1 hour.
Light a gas grill. Wrap the wood chips in heavy-duty foil and pierce the packet all over with a skewer. Add the packet to the grill. Cover and let the chips begin to smoke, about 5 minutes.
Grill the lamb, covered, over moderately high heat, turning occasionally, until the chops are lightly charred in spots and tender, about 18 minutes. Transfer the lamb chops to a platter and serve.
The seasoning paste can be refrigerated for up to 1 week.
