I've had trouble finding info on the monk skills from the beta build that was at the press event. So far I've only found Blizzplanet to have any write ups. Here is a what they had posted over there, feel free to add in any info you may find elsewhere.
Spirit, defensive focused resource, base attacks generate spirit, precious resources, attacks have three stages to feel dynamic, can mix up abilities
Deadly Reach, hit enemies right before they reach you, control position
Exploding Palm, third hit is $$ applies a DoT, and if it kills them they explode + do damage to area
Mantras, ability unique to monk, buff extends to her and allies, big dodge bonus
Tempest , can’t get surrounded, slows enemies in path
Inner Sanctuary, monsters can’t pass through and creates choke points, etc. Allows for high control.
Seven sides strike, big spirit spender, invulnerable for short period of time does massive damage to groups of enemies.
