Oven roasting bags like you would cook a Turkey in is your friend. I spice up a brisket and put it in a bag with some Worchester sauce and some liquid smoke. After it is cooked I put it in the pan and cover and refrigerate it over night. I then skim off as much of the fat as possible form the brisket and the drippings. Slice the Brisket across the grain and put back in the pan with the drippings. Cover with foil and reheat in the oven. I don't really have a specific recipe I just play with the spices.
