I don't write much het because most of my hetships are canon and like kyuuketsukirui says below, I find canon pretty satisfying in that respect.

the irony of writing an Amazon's soulmate as male doesn't escape me ;)

Hey, believe it or not, I'm pulling for Gail Simone to do something awesome with Diana/Tom, and that's anathema to a lot of fans.

I've always liked the Diana/Steve relationship, whether romantic or friendly, and I wish he could have a presence in her current comics. I'm a sucker for the from-different-worlds kind of relationship, where they learn from each other. I also think it's important for Diana, even more so than Bruce or Clark, to have deep connections to 'ordinary people'.
