Hm. I've not tried a Ranger type, but I think you should take Stealth as your specialisation, because you will need Marksman and Sneak and Light Armour among your Major skills, and these will help build up your Agility and Speed Attributes.
I would suggest you also take a Melee weapon skill to build up your Strength. That gives you 4 of the 7 skills, but only 3 attribute builders. But not all your Attribute builders need to be Major Skills.
A Ranger doesn't need a huge amount of Intelligence or Magica, but you need some, so take Restoration, which will add to your Willpower (thus adding to your protection against magic). And it is a darn useful magic as well!
That makes 5 major skills, and 4 Attribute builders.
Your own personal preferences are the most important to consider, though.
