In the case of the magnifying lens, the magnification power is determined by the following relation: I=250/F, where F is the lens focal length. To increase the magnification power i.e. magnify the image, you need to decrease the focal length (so that as F decreases, I increases).

You can add a barlow lens to the lens you are using.
Oh wait, we're assuming a theoretical homework problem fully adjustable telescope?

Think about a movie/slide projector. The further you move it away from the wall, the bigger the image becomes. This is similar to what happens with lens distance.
