Use ethier dry heat like the burners on your kitchen stove or steam. With dry heat be sure and give a healthy covering of some kind of grease or shortneing. Rub it into the wood well then slowly heat the piece. Watch for charring. Have pot holders on both hands and test bend the wood to see if it's become hot enough. When it has , bend it and hold it there until it cools, or bend it and run it under cold water to cool it quicker. You can also use some type of form to bend it. Bend it alittle farther then you want it to be , as it will revert back alittle once you take the pressure off. If you over-bend it you will obviously break it.
Steam is somewhat safer, as you cant over-heat and char the wood. Get a pot of water, put the area of the wood you want to bend over the pot, with the sides of the wood resting on the pot, then cover it with aluminum foil. Turn on the range to high. Make sure there are no gaps in the covering, as this can cause problems in the heating. Even so steam will be pouring out of the pot, thats not a problem. Depending on the severity of the bend and how thick the piece is let it steam for anywhere from 30 mins to 1 1/2 hours. Once done take it off and quickly bend the wood. You need to be quick, within 25-30 seconds the wood will be too cool to safely bend the wood. Some woods like Osage can easily be bent with steam , and will keep their full bend. Others, especially the white woods like ash, oak, hickory etc are best left in a form until the wood dries from the steaming. This isn't always nessacary, but at least don't stress/bend the wood until it's had a couple days to dry out again.
