What issue is up for vote at the beginning of "Star Wars: Episode II - Attack of the Clones"?

At the beginning of Star Wars: Episode II – Attack of the Clones, the Senate is voting on creating an army for the Galactic Republic.

The proposed military force is tied to growing unrest from the Separatist movement. Until this crisis, the Republic had no large standing army, and security responsibilities were largely handled by local planetary forces and the Jedi Order.

Senator Padmé Amidala is traveling to Coruscant to oppose the measure, believing that creating a Republic army would escalate tensions and make war more likely. Her assassination attempt prevents her from participating in the vote, setting off the mystery surrounding the clone army.

A common mix-up is to call this opening vote a vote to create the clone army specifically. The Senate is initially debating the creation of a Republic army; the clones are revealed later, after Obi-Wan Kenobi discovers Kamino and its vast military force. Chancellor Palpatine ultimately receives emergency powers and uses the clone army when the Clone Wars begin.
