Bravo on the original concept! I'm intrigued to see whether you go full zealot or some form of spy among the ranks... Though, I doubt sudden, loud outbursts of "HAIL IFRIT! BY FIRE, BE CLEANSED!" would be all that subtle. Maybe if you wear a moustache.
Mentally: From what I can gather, the mentality of a tempered is the greatest change they undertake. The mind of the individual seems to warp, suiting the Primal's ideals (ie. Ifrit's immense zealotry, Garuda's thirst for power & dominance, Ramuh and Titan's protectiveness, though the latter two do so in very different ways). This does not mean, in my view, they would be as full on as their primals. I mean, you don't see an Ixal wearing a bra made of feathers being a bit of a dominatrix, do you? So it's more their ideals, I would say.
Magically: I figure this comes as part of their fanaticism. ie. Rather than having a gift bestowed upon them, in an attempt to please their primal deity, they will study tirelessly the element of their patron. So, rather than some "divine gift", I would say this, too, is an attempt to be as alike to their primal as possible.
Plus, if that's not enough, think of it this way. You have been tempered by, say... Leviathan. Despite having a stupid name now, Mrs Scaleback, it is highly likely you will view the element of water as superior to all others. As such, which magic are you most likely to want to master? Water.
Communication: I have no source on this but I would say, yet again, one word: Fanaticism. History has proven this time and time again. Devote yourself to a cause or deity too much and you will start to believe you are their "Hand" in the mortal plane. There may well be some form of mental echo the Primals use to speak to the tempered, but I would bet the tempered are just doing what they think their god would like/they have been commanded. Somebody questions why? "BECAUSE IFRIT."
