There is a tremendous amout of energy within Wonder Man. He'd have to hit him with some kind of beam to drain his energy. If WM is flying around, it would be pretty hard to hit him.
Wonder Man is stronger, faster, and has beaten on the Avengers and the West Coast Avengers on more than one occasion. He survived the Nega Bomb, getting put through a planet and sun, all of which would kill Iron Man.
Considering the fact that Wonder Man is energy, and Iron Man has manipulated just about every form of energy in the MU, I'd give the edge to Tony Stark.

His body is constantly being permeated with ions. Ions are everywhere. His body is not energy. Ions are constantly flowing through his body which gives the him the appearance of being composed entirely of energy. It may seem and look that way, but his body is quite solid. Iron Man may absorb large amounts of energy, but he'll soon find out it'll be nearly impossible for Iron Man to siphon energy when he is speed blitzed and has his head ripped off. Yes I'm a Wonder Man fanboy, and I have a bunch of his comics, and if Wonder Man was serious, it'll be over, quick. especially if it's current Wonder Man. He's got a better handle on his powers now than he did 10 years ago.
Wonder man is one of the most strong individuals in marvel universe, but iron man could take anyone in a fight. He did beat the hulk , thor or silver surfer. If he could beat those people , he could beat wonder man. Any of those two people could be the winner in a battle.
