Not sure I can give any pieces/exercises that fit the bill, but I would recommend going back to pieces of music that you were playing a year ago, and trying to play them again while looking at the music and NOT looking at the keyboard.
Some other things you might have a go at:
Try playing scales and arpeggios that you have previously studied - but play them without looking at the keyboard.
Do the same with some of the standard cadences (I-IV-V-I etc,) - and see if you can play them without looking at your hands.
Easier than the above: try closing you eyes, and feeling for the keys - I found that learning to quickly identify (by touch) the black keys F#, G#, A# with fingers 2, 3, 4- was very useful. Then try playing the B major scale using the standard fingering - but not looking at the hands!
Good luck.
