I've only had one macro for the Paladin and it hasn't really changed since Wrath has came out because it's worked so well. It works well for 5 mans, AoE Pulls, Raids, you name it. One thing I'm noticing is starting to be a problem witha 5k plus gear score is that if I run a heroic, the mobs aren't able to hit me enough that I need heals at all which in 1on1 situations sanctuary is unable to keep my mana up so I'm always out of mana it seems and have to switch to seal of wisdom for some pulls.
Paladin AoE and Single Target Tanking
Since Paladin's are more of a reactive or passive tank requiring mobs to hit them to generate a lot of threat and don't do a lot of damage compared to the other tanks, the macro is pretty simple. You will still have to pull with Avenger's Shield or whatever you like to pull with, drop a Consecration if you wish (Consecration can actually be added into the castsequence if you want, and do your judgements / cooldown abilities manually. But this one button macro for the Paladin makes it a lot easier to just focus on those things and not worry about the core of threat generation.
Your biggest challenge is going to be mana management, you'll probably end up judging wisdom, toggling seal of wisdom and seal of vengeance a lot, and hitting divine plea. This is not an issue for melee raid mobs that actually hit you hard enough that you require a heal.
