Mutually coupled inductor modelling in cadence
please suggest me, which method is best suited for WPT coil modelling
  in cadence


I can't tell you which works best in cadence because I don't use cadence but, I'd stick with the coupled inductor model and set the turns ratio by setting the inductor ratio appropriately i.e. if you want a 10:1 turns ratio, you use a ratio of inductors that is \$(10:1)^2\$ or 100:1.
