I'd use root notes- basically the same frets as the guitar is playing in the power chord. Fo example- if the guitar is:

7 x 8 the bass could play 5 5 5 5 5 5 5 5 on the low E
7
5

However if you want to mix it up a bit add some other notes in from the same scale as the bass. Hope that helps. If you can, post a link to your Guitar pro 5 and i'll have a look
