If you purchased a ham that's been precooked, you can either serve it cold, or you can add a glaze and cook it between 20 - 30 minutes in the oven @ 350o F. Remember, the meat has already been cooked, you're just heating it up so a long cook time isn't needed. Some really good glazes (IMHO) include Dijon mustard and/or honey/brown sugar, but don't be afraid to experiment.
Cover with foil and put in a 325 degree oven and reheat at approximately 10 minutes per pound.

You reheat a smoked ham for ten minutes per pound. Add a glaze to the smoked ham during the last 30 minutes of the reheating time.
at 300 to 350 is a good temp and to tell if its done u need a cooking temp taker and when u see that the ham is at 330 degrees it finish
For pre-cooked ham, you need an internal temperature of 140 degrees F. For a non pre-cooked ham, you should cook it until the internal temperature reaches 160 degrees F.
12 to 15 minutes per pound for a 12 pound ham at 325 should do it. For more info try all recipes .com and search roasting times.
For an uncooked ham the temperature needs to be 160 degrees. Personally, I find that removing the ham from the oven when the temperature reaches 155 degrees, and letting the ham rest for 15 minutes produces a better product. The internal temperature will rise the extra 5 degrees while resting and allows the juices to become more evenly distributed. If the ham is partially or fully cooked, the internal temperature need only be raised to 135 - 140 degrees.
2 1/2 hours. Here's how: Preheat the oven to 325, place the ham on a rack in a baking dish with a little water in the bottom. Wrap in foil, bake for about 2 hours, or until the internal temperature is 135 - 140 degrees. Take off the foil, glaze the ham, if you like, increase the oven temp to 400 and bake for another 20 minutes or so, until the glaze is set.
If food that should have been refrigerated was left out at room temperature overnight, it should be discarded.
You can reheat fully cooked smoked chicken in the oven on a low temperature. You can also reheat this type of chicken in the microwave.

The best way to reheat lasagna is to use a microwave oven. You should heat for about 2 minutes at max power per serving, covered in plastic film to avoid it from getting dry. If you reheat it in a traditional oven, do it at a low temperature (140ºC), covered in aluminum foil for about 20 to 25 minutes. You can use a knife to poke it trough the center to check the core temperature.
As long as the food was cooked properly the first time and proper storage precautions were observed, then there is no set temperature that must be reached in order to safely reheat it. Warm to whichever temperature you desire in order to enjoy it.
