Obviously one for the theists here...which Gods/Goddesses do you have a current relationship with? Or want to get to know/develop a relationship?
Hekate is currently the sole deity that I am meditating upon and conversing with on a semi-regular basis (generally once a week.)
However, my prime interest is deities from Irish and Welsh pantheons, with a particular focus on certain Gods and Goddesses with particular skills and correspondences.
Manannan Mac Lir of the Irish pantheon has grabbed my interest (appears to be more or less the same deity as Manawydan in the Welsh pantheon.) I haven't yet done anything to develop a practice with him, but I'm hoping to as time goes on. There are other deities that catch my interest too.
