You didn't say which version of OS X, but here is an article from Apple on Target Disk Mode in Mavericks. Probably works the same in Yosmite, but I can't say for sure.

Hello and welcome to the forum! Please provide more information about your computers, e.g. model years, type of ports available on each, what kind of data is being transferred, OS X installed, and the nature of your home network (which might be another way to transfer your data).

As to the hardware needed, if your laptop has a thunderbolt port (and I'm assuming you have an older iMac w/ a firewire port), then a cable adapter such as the one below could establish a wired connection - now you'll have to provide more information as asked above as to the best way to get your data from one machine to another?
