I don't know if there is much you can do. I would try opening up your mouth more or as much as possible to get most of your sound coming from you mouth. Mabye set the mic stand a bit higher and tilt your head upwards. Really concentrate on getting your voice loud enough to overcomensate the nasal sound.
I wouldn't worry about it too much, you can just make it "your" sound. Look at Lenny Kravitz, cool cat indeed, but listen closely to his vocals. He always sounds like he's got a cold or his nose rings interfere with his vocal.
