Yes I made a new Spanish translation of "Holy God" for the Oramos Cantando / We Pray in Song hymnal (no. 511). The OC/WPiS text committee was not satisfied with the translation of Pablo Filós, which appears in the 1978 Himnario Bautista because it did not follow the 7 8 7 8 77 meter of the English text.
Don't forget: Holy God, We Praise Thy Name is an English translation of a German rendering of the Te Deum. Any of those (especially the Te Deum) could be considered the beginning point for the translation.
