Don't touch the keys. Close your eyes if you like, and imagine the music you are working with. Listen to it in your head. Listen very carefully. Slow it down if you like, or feel the rythm and tempo if you like.
If the piece is not "grade 1" it probably has more than one line. Have you listened to them separately? Have you investigated the harmonies? Have you listened to the chords, explored the richness and full sound of them? Have you tried to achieve the most beautiful, rich sound you can, or have you "just played it"?
When I fully immerse in the music, I can listen to a single phrase or a few phrases, and when I do it right I feel that my heart follows the beat and the feeling (just an illusion, I hope, but still!) I get emotional. Sometimes I see scenes or pictures, sometimes it is just a feeling.
Another trick to stay on track is to work with very short sections. Observe all your movements (and by all means, also observe your posture and your breathing) and be very aware of what you are doing in EVERY movement. In this way you cannot think of anything else than what you are doing.
