Back when WotC was trying to figure out how to do the psionic caster subclass for Tasha's, they created a "psionic" school that contained a bunch of wizard spells that they felt were psionic-themed. When creating this list, they said this:
Psionic Spells
Spell selection is part of what defines a wizard and their individual fields of expertise. When creating your Psionics wizard, consider spells that are thematically appropriate for that tradition. Psionics as a theme generally includes spells that do the following:
• contact or manipulate minds
• allow the caster to perceive distant locations or planes
• alter perception
• move objects and creatures
• teleport
• deal psychic or force damage
The list was wizard spells pulled from the PHB and Xanathar's, with some new spells that eventually did or didn't make it into Tasha's. I think it wouldn't take much to use these guidelines and pepper the list with additional spells pulled from the other classes and make a functional psionic list. If the list is too thin, it could be bulked up with some broadening of the theme (for example, spells to represent metabolic mastery like alter self) or new spells added.
