From Queen's Peril which takes place during TPM-
"You sense something," Windu said. "Something you haven't told anyone else about."
"So clever you are, Master Windu," Yoda said. "And so close to the truth. But think you not in the right direction, I say."
"What other direction is there, Master?" Windu asked. "Either you sense something or you sense nothing."
"Open your mind, Master Windu," Yoda said. "If sensed nothing is, something must it be."
"No," he said finally. "Nothing can never be something. They are opposites."
"So sure you are," Yoda said. "Reassuring, it is. Never so sure of myself am I."
"You think differently?" Windu said. It was starting to feel like a debate with Qui-Gon, and neither of them really enjoyed those.
"I think I sense nothing," Yoda said. "Presume anything after that, I do not."
"I trust your judgment, Master Yoda," he said at last. "I know if there is an answer, you will find it."
Yoda didn't respond. Instead, he closed his eyes and reached for the calm of the living Force flowing through him. After a few minutes, he felt Windu get up and leave him alone with his thoughts, which was his favorite place to be.
The light surrounded him, the dark a comfortable distance from the limits of his perception. And yet there was something; rather, there was nothing. And it eluded him completely.
Even though Yoda doesn't realize it, the nothingness he is sensing is Sidious's concealment. So I guess Yoda was the first Jedi to sense Sidious (if you want to call it that.)
