First, I'd say drop the Frenzy. If you're a tank, that means you should be taking the hits and leave the damage to the rest of the party. That means with Frenzy on, you die twice as quick. This is especially bad if they shatter enchantment you, as you lose both mending and take a huge chunk of damage. I'd also suggest dropping mending and instead going for healing breeze. You're also missing restore life. If you're partying with other people, there is NO EXCUSE to not pack some sort of res, especially if you are a monk primary or secondary. Warriors are generally the last to die, and most of the times the success of the mission depends on YOU rezzing everyone else.
I dont' suggest using any attack skills that cost mana, thus drop smite and Power attack. Your limited mana should be used for keeping yourself and your party alive. Your extra 20-30 damage isn't going to make a difference, but that extra 40-50 points of healing will. In fact, I suggest you drop smiting all together, because all u'd have left is bane signet, and the long cooldown + low damage is not worth spending any points into smite for.
When you get to beacon's perch, you should be getting balthazar's spirit. Use that as it is one of the best w/mo skills IMO. You lose 1 pip, but you'll be gaining far more mana from it than you would with that 1 pip not to mention the extra adrenaline. This is pretty much one of the few enchantments worth maintaining.
