Double double Palomar knot

[TubeDude]

Or...you could use your regular knot...improved clinch or whatever...after running the line through the hook eye two or three times.  Even Nanofil holds solid with a double or triple eye loop.

Or...you could make some custom tube jig heads with the eye centered in the lead to create a natural horizontal presentation.  I have a spinner body mold that I have modified to accept jig hooks...and to make tube jigs with the hook eye centered...as in the attached pic.  Will loan it to you if you wanna make a few...1/8 oz., 1/4 oz. or 3/8 oz.
