You The notion of real and imaginary part are very related to the particular polynomial x^2+1, so for me it makes sense that there is no suvh method for an arbitrary field extension.
Anuway, you can turn v into a polynomial on the undeterminate j:
sage: v.parent()
Finite Field in j of size 10354717741769305252977768237866805321427389645549071170116189679054678940682478846502882896561066713624553211618840202385203911976522554393044160468771151816976706840078913334358399730952774926980235086850991501872665651576831^2
sage: P = v.polynomial()
sage: P
