HI, i play in a band. I know i could buy a new amp but i rather try to make mine more powerful. So i have a ibanez val-bee (5 watt tube amp) and really like the sound, how can i make it more powerful for band pratice?
Short answer, you can't.

Long answer, you could extensively modify it, but this would be plain stupid. You could try running it through a cabinet or getting more efficient speakers, but I still don't think a 5 watter is gonna cut it.
I don't give a shit if you listen to me or not
Its a 5 watt amp no easy way to make it have more watts. It does have an fx loop. A trick I use with an amp I have is put an EQ pedal in the loop and crank the gain on the pedal it will make it quite a bit louder. But the speaker on the little thing is going to be a bit limiting. Your probably just gonna have to break down and buy something bigger.
Buy a PA and mic it.

I've had tube amps for a while now, but never actually had any go down on me

maybe you're not saying the right things? an amp likes to know you care.

you can always mic it through the PA system

add an extra power tube or replace the speaker

or both

but for the price and time both would take why not just get a new amp?

get a cheap marshall... my MG15DFX has a button that simulates the sound of one of the expensive tube marshall amps.
