Some exercises:
Right hand, play all the major chords chromatically from C over two octaves. Then all the minor chords. Then do them in their second inversions and third inversions. To a metronome, slowly at first.
Left hand : Practice Alberti basslines. Alberti is a broken, or arpeggiated chord, where the notes are played in a certain order - i.e. lowest, highest, middle, highest - finger numbers 5, 1, 3, 1. For example, to do C major in alberti it would be
C G E G
5 1 3 1
If you don't know your finger numbers then here:

And try that, going through the cycle of fifths. Or chromatically. Do both.
