The post below explains the Mantra Vidhi to attempt to invoke the Sulochana Yakshini and is based upon the Mantra and Siddhi Sadhana procedure provided by Kapil Pramanik, which, I have translated into English.
The Mantra Prayoga should be performed on the banks of a river[ Nadi Kinare] by chanting the Sulochana Yakshini Mantra, given below 300,000 times using a Rudraksha Japa Mala. After, completing the Mantra Chanting the Sadhaka should perform Dashansh Havan [One-Tenth of the Number of Mantra Chants, which is 30,000 time]. As the offering to the Havan is not mentioned, it should be taken to be an Ahuti of Pure Ghee [Clarified Butter]. It should be performed by offering a spoon of Ghee to the Havan while chanting the Sulochana Yakshini Mantra
If the Sadhaka is successful in pleasing and invoking the Sulochana Yakshini, she blesses him and presents him with a Jadui Khadaun [ Magical Sandals, Slippers or Shoes], which enable him to travel through time and space or the Universe[Bhumandal Ka Safar] wearing these Magical Sandals.
Note- Apart from the Sulochana Yakshini Invocation Mantra, the Tantra has not prescribed any other form of Puja-Vidhi or Tantra in order to perform this Sulochana Yakshini Mantra Experiment.
