If you are going smiteless y ou obviously got a leash AND/OR you are playing Shaco/Nunu; and then  you are going to:

a. ... invade the closest enemy buff.

b. ... rush your other buff for a gank.

There is no other reason for going smiteless. If you are just gonna farm, and you are SURE you aren't getting invaded (having vision of the other jungler or wards nearby), then you can just spam Smite. I usually initiate buffs with smite if I'm REALLY confident I'm not getting invaded, though it's risky.
