He had no such plan.
It's worth remembering that, as far as we know, Voldemort was only the second person in history to make a Horcrux. It wasn't widely known what happens to a wizard who dies after creating a Horcrux. Even Voldemort probably didn't know at the time. All he knew is what he learned from Horace Slughorn.
A Horcrux is the word used for an object in which a person has concealed part of their soul.”
“I don’t quite understand how that works, though, sir,” said Riddle.
His voice was carefully controlled, but Harry could sense his excitement.
“Well, you split your soul, you see,” said Slughorn, “and hide part of it in an object outside the body. Then, even if one’s body is attacked or destroyed, one cannot die, for part of the soul remains earthbound and undamaged. But of course, existence in such a form...few would want it, Tom, very few. Death would be preferable."
(Half-Blood Prince, Chapter 23, Horcruxes).
It seems that Voldemort didn't know exactly what would happen should he ever have to rely on his Horcruxes until his downfall at Godric's Hollow.
“I miscalculated, my friends, I admit it. My curse was deflected by the woman’s foolish sacrifice, and it rebounded upon myself. Aaah...pain beyond pain, my friends; nothing could have prepared me for it. I was ripped from my body, I was less than spirit, less than the meanest ghost...but still, I was alive. What I was, even I do not know...I, who have gone further than anybody along the path that leads to immortality. You know my goal - to conquer death. And now, I was tested, and it appeared that one or more of my experiments had worked...for I had not been killed, though the curse should have done it. Nevertheless, I was as powerless as the weakest creature alive, and without the means to help myself...for I had no body, and every spell that might have helped me required the use of a wand..."
(Goblet of Fire, Chapter 33, The Death Eaters).
Voldemort is quite open about his ignorance of how Horcruxes truly work and what state he was in when he was depending on them. He wasn't prepared for the circumstances in which he'd be a ghost-spirit because there was no real precedent. He was pushing the boundaries of experimental magic. Nobody could really have predicted what would have happened to him.
Additionally, of course, Voldemort never expected to have to rely on his Horcruxes. They fed his ego by reassuring him that he was immortal (and therefore superior to every other wizard). They were a failsafe. But Voldemort was confident enough in his own abilities that he never expected to have to rely on them. He never expected to die. As such, he never prepared for the circumstance he found himself in. He subsequently hoped that one of his Death Eaters would come looking for him but he didn't prep them for that eventuality in his earlier life because he never expected to die in the first place.
