Ah, I had missed that this was about the monk type, not the monk class.
Well, my favorite monkish build right now is this guy:
Monk 6/Shou Disciple 4/Unarmed Varient Swordsage 4/Master of Nine 5. Offensively you're basically a Monk only far far better, and there's lots of very handy manuevers available to you (including Iron Heart Surge and, if you want it, White Raven Tactics, though honestly I don't think the latter fits the martial artist feel).
