Sorry, miss a command \addcontentsline{toc}{chapter}{xxxxxxxxx}
to insert to the TOC, manually
after table of contents (from Lyx)
\clearpage
\listoffigures
\addcontentsline{toc}{chapter}{List of Figures}
\clearpage
\listoftables
\addcontentsline{toc}{chapter}{List of Tables}
\clearpage
for \clearpage you may use (command from LyX) Insert > formatting >
clearpage
\listoffigure = Insert > List/TOC > List of Figures
\listoftables = Insert > List/TOC > List of Tables
