He really just plays the same chords, D, Em and G he normally would, only in this case Gm, Am and C since its 5 frets up. Like I said you put a capo on the 5th fret (crucial) and you really play it exactly the same as normally.
So: G Am G C
E---7----(5)----7-----8---
B---8----(5)----8----(5)--
G---7----(5)----7----(5)--
D--(5)----7----(5)---(5)--
A----------7-----------7---
E---------(5)----------8---
(5) means capo'd string
See? Not exactly rocket science.
