Elemental paladin

Can anybody help me with my current Templar build. This game has such a huge talent tree that I feel lost when trying to decide what path I wanna take and/or abilities. The idea I am trying to go for is a Elemental Paladin with a focus on heavy def. (probably become a tank on higher difficulties) and specs in maces. I'm probably going to go with a cold spell for my elemental damage as I love the freeze effect of glacial strike.

As it stands that's what I could come up with after an hour or so. Even after looking it over and over twice already I feel like my chosen paths are probably not even that great for my idea.
