You should practice chord progressions in every key, every day. practice:
D/FACE
G/FABE
C/EGBD
then go up a half step till you have gone through all 12 keys.
also practice
D/CEFA
G/BEFA
C/BDEG
going up a half step through all 12 keys.
This may seem hard at first, but once it becomes easier, you will find your playing has become much better.
