After you climb Sky Peak the second time and recruit Shaymin Land Forme, you will need a Gracidea to change it into Sky Forme. There is a Shaymin in the Shaymin Village giving out Gracideas for free. Talk to all the Shaymin and you should be asked if you want a Gracidea.

One of the Shaymin in the Shaymin Village will give you a Gracidea if you talk to her. Use this Gracidea on your Shaymin in a dungeon to change it into its Sky Forme.
