The Adath Israel practice is to recite the Individual’s Kaddish when a minyan is not present in one physical space. We pray for the day when we can all safely daven together at our shul.
“Kaddish for an Individual”
from Seder Rav Amram Gaon (9th century Sura)
Over all may the name of the Supreme King of kings, the Holy One, be magnified and sanctified, praised and glorified, exalted and extolled, in the worlds that He created-this world and the World to Come – in accordance with His will and the will of the whole people of Israel.
Rock of worlds, LORD of all creatures, God of all souls who dwells in the spacious heights and inhabits the high heavens of old. His holiness is over the throne of glory and over the Hayot.
Therefore may God’s name be sanctified among us in the sight before God a new song, as it is written: “Sing to the LORD a new song, for He has worked wonders.”
Al ha-kol yitgadal v’yishtabah v’yitba’ar v’yitromam v’yitnasey sh’mo shel melekh malkhey ha-melakhim ha-kadosh barukh hu ba- olamot she’bara ha olam ha-zev v’ha-olam ha-ba.
Kir’tzono v’khir’tzon kol amo Yisrael.
Tzur ha-olamim adon kol ha- beriyot elo’ah kol ha-nefashot ha-yoshevb’merhavey marom ha-shokhen bishmey sh’meykedem, k’dushato al kisey ha-kavod uk’dusahto al ha-hayot.
Uv’kheyn yitkadash sh’mo banu I’eyney kol hai v’nomar I’fanav shir hadash ka-katuv shiru I’Adonai shir hadash ki niflaot asah.
