None of these are as explicitly Trinitarian as is expected in a doxology, but it is what they are intended for:
We raise our shouts, O God, to thee (Isaac Watts) We raise our shouts, O God, to thee, And send them to thy throne; All glory to th' united Three, The undivided One. Hosanna! let the earth and skies Repeat the joyful sound; Rocks, hills, and vales reflect the voice In one eternal round.
Thou art the first, and thou the last (unattributed) Thou art the first, and thou the last; Time centres all in thee, The Almighty God who was, and is, And evermore shall be. To thee let every tongue be praise, And every heart be love; All grateful honours paid on earth, And nobler songs above.
Our God is worthy to receive (unattributed) Our God is worthy to receive Honour and pow'r divine, And blessing, more than we can give, Be, Lord! forever thine: Let all who dwell above the sky, And air, and earth, and seas, Conspire to lift thy glories high, And speak thine endless praise.
Offhand, mining Hymnary, I've not found a CMD doxology (an 8-line doxology is a challenge). But combining two CM verses from Charles Wesley, one can use:
Hail, Father, Son, and Holy Ghost, One God in persons Three; Of Thee we make our joyful boast, Our songs we make of Thee. Present alike in every place, Thy Godhead we adore: Beyond the bounds of time and space, Thou dwell’st for evermore.
So, if you mine old PD Common Meter hymns for a doxology, combine with another CM verse of general praise to the Godhead, either before or after - the above is an illustration of the latter (and was set that way by Wesley, who began the text with a doxology rather than ending with it).
