If you already have your basic open chords down, but are having trouble with barre chords, try fretting your open chords with the same fingers you would use for the barre chord.
For example. Take an open E-major. Normally you would fret it with your index, middle and ring finger. Just move everything down a finger so you are playing the same strings and frets with your middle, ring and pinky finger.
Practice a few songs using open chords with this kind of alternative fingering until it feels fluid. Then you can just take each chord shape, slide it down the neck and add the barre.
