some that i've found for Tamla are, from Sharon Davis' book:

Tamla 260 Marvin Gaye & Kim Weston 'Side by side'

Tamla 323 Ashford & Simpson "Nick and Val"

Tamla 369 Marvin Gaye "Love Man"

Tamla 370 Tata Vega "Givin' all my love"

Tamla 377 Stevie Wonder "Stevie wonder's original musiquarium"

Tamla 388 Smokey Robinson "yes it's you lady"

plus wasn't marvin supposed to release a Copa album? it doesn't appear to have been assigned a Tamla number so maybe it never got that far
