Applying to Law School next year--how to get LoRs.

I’m a sophomore in college but graduating as a junior next year. I have done well academically (3.95 GPA) but haven’t really gone in for office hours/ gotten to know my college professors that well.

In addition, I have only had one job for a few months and my boss moved to China.

What steps can I take now to develop better relationships with professors so I can ask them for LoRs next year? What is the protocol for this because normally I form relationships with my TAs?
