Wow, I must really underprepare.. unupgraded leather armor sans cloak, lvl 2 or 3 wooden tower shield, level 2 or 3 flint spear. Deer and boar meat plus honey. Usually start off with one fire arrow just to get him mad and a bit easier to see. Stabby stabby stabby, melee range throws, rinse repeat; done in about half a dozen cycles depending on your aim.
