One idea I've had with shapeshifting and empowered abilities is to have 3 "tiers" for all abilities.

The first tier is standard abilities, the second tier is shapeshifting abilities and the third tier is empowered abilities.

Shapeshifters will be able to use the other version of tier 2 abilities when transformed, but not tier 3.

Empowering like Mantra and Rengar's passive will be able to use the second versions of both tier 2 and tier 3 abilities when triggered/activated.

Optionally, the third tier could be separated into two tiers, one for weaker empowerings like Rengar's and Renekton's and one for stronger like Karma's and Heimerdinger's.
