In Morrowind, Battlemages used axes (primarily one-handed axes, due to their balance between power and speed), with heavy armor and Alteration spells for protection. Destruction is the other primary method of attacking, with Conjuration and Mysticism providing support. Enchant and Alchemy round out the support skills, with potions providing healing and buffing in lieu of Restoration, and Enchant making the use of enchanted weapons and items more efficient. The class also uses long blades as a backup weapon, and marksman weapons, which I personally think is a bit redundant when paired with Destruction, but which allows for a ranged attack when out of magicka (useful, as magicka in Morrowind does not regenerate).
In Oblivion, Battlemages are masters of melee weapons, but have no armor skills. NPC Battlemages use a wide variety of weapons and armor styles -- some prefer heavy armors for protection, while others like light armors for mobility; typically they use the heavier one-handed weapons, like longswords, maces, and war axes, though stronger, heavier weaponry can be temporarily summoned. They use Destruction for offense and Conjuration and Mysticism for support (Mysticism's spells changed somewhat between Morrowind and Oblivion, so in Oblivion Battlemages use Mysticism to dispel buffs and summons from enemies while removing hostile magic from themselves, and protecting themselves from enemy spells through spell absorption and reflection). Alchemy and Alteration provide buffing and healing.
So, in Skyrim, I think a Battlemage would specialize in Conjuration, Destruction, Alteration, and one-handed weaponry (since this leaves you a hand free for spellcasting). You can either eschew armor for mobility, or make use of Alteration's shield spells to boost your armor rating, since you probably won't have as many perks to put into armor, as magic is very perk-dependent.
It's your choice on whether to use Alchemy or Restoration for healing. Restoration has some useful defensive capabilities, and healing spells are very effective in Skyrim; Alchemy is more versatile, but requires a lot of investment, so it may not see its full potential realized if it's just a side skill.
There is no NPC Battlemage class in Skyrim, so I couldn't tell you what NPCs use. There are Sorcerer and Spellsword classes, however, which both use magic and armor in tandem. Sorcerers are essentially "tank" mages who use heavy armor, and Spellswords are more like warriors who can use magic (primarily Destruction and Restoration -- through Destruction's crowd-affecting power and Restoration's healing and magic protection, the warrior's weaknesses are covered). There's also a Witchblade class, which is similar to Morrowind and Oblivion's Witchhunter class, except with a focus on one-handed weapons over archery (in essence, a lightly-armored skirmisher who makes up for the weaknesses of relying upon a fast one-handed weapon with Destruction's additional damage, Conjuration's distractions, and Illusion's crowd-control), and a Nightblade class, which is a thief-like class which uses Destruction and Alteration to boost a traditional thief's combat capabilities.
