Beware, older languages below! The languages below were invented during Tolkien's earlier period and should be used with caution. Remember to never, ever mix words from different languages!

yanta

noun. yoke

The Etymologies of the 1930s had ᴹQ. yanta “yoke” derived from primitive ᴹ✶yantā under the root ᴹ√YAT “join” (Ety/YAT). However, in Tolkien’s later writings, Q. yanta was translated as “bridge” instead (LotR/1123).

Conceptual Development: In the Qenya Lexicon of the 1910s Tolkien had ᴱQ. {yatra >>} yarta “yoke” under the early root ᴱ√ẎATA “join” (QL/105), as well as ᴱQ. yalta “yoke” derived from ᴱ✶yḹta under the early root ᴱ√YḶTḶ (QL/106). In the Gnomish Lexicon also from the 1910s, Tolkien had ᴱQ. yalte as cognate to G. galt “yoke” (GL/37).

Neo-Quenya: Of the options above, I think ᴺQ. yalta is the best choice for a Neo-Quenya word for “yoke”, as a cognate to ᴺS. ialt. For example, Helge Fauskanger used both yanta and yalta for “yoke” in his NQNT (NQNT).
