[MCU] How did Thanos get the IG? Wasn't it in Odin's vault?

At the end of AoU you see Thanos grab the IG from his own lair.

The Infinity Gauntlet is ... just a glove. It's the Infinity *Stones* that have power. You could embed them in the hilt of a sword and make the Infinity Sword, or put them in a tiara and create Infinity Diadem, or hell, glue them to your dashboard and make the Infinity Toyota.

The thing in Odin's vault may have been used to house the Stones at one point, but as we know from basically every Marvel movie, they aren't there now.
