Put the mixture in the bottom of the wok, and arrange a rack 5 cmes over it. Transfer the chicken, breast side up, to the rack in the wok. Heat wok, covered, over mod-high heat for 5-6 minutes or until it begins to smoke. Smoke the chicken, covered, for 6 minutes. Turn chicken breast side down, and smoke it for 6 minutes more.
